Hes galdric,
to be honest, I don’t quite understand what you mean by reddish.
The dark pink of the nose and torso (the naked pottery?) seems fine to me. Also the white highlights.
The stickers as well, there is one that is neutral white (or close to it).
That tells me that it’s not a general issue of a color shift or so.
What I can’t see in the texture file are the dark rusty orange areas on the forehead and the side of the face down to the shoulder (?). Is that what you are missing? If those are really glossy (hard to judge with only one image), then I fear that might be the reason.
